DEINKING A CELLULOSIC SUBSTRATE USING MAGNESIUM SILICATE

摘要

The present invention provides for a composition comprising: a) activated magnesium silicate; b) optionally a suspending agent for said activated magnesium silicate; c) water,- d) optionally an emulsifier,- e) optionally excluding caustic soda; and f) optionally excluding hydrogen peroxide. The present invention also provides for a composition comprising: a) magnesium silicate; b) a suspending agent for said magnesium silicate; c) water; d) optionally an emulsifier; e) optionally excluding caustic soda; and f ) optionally excluding hydrogen peroxide. The present invention also provides a method for deinking a cellulosic substrate, using the composition described here above.
